btrfs-progs: fix max mirror number error for chunk-recover 

When run chunk-recover on a health btrfs(data profile raid0, with
plenty of data), the program has a chance to abort on the number
of mirrors of an extent.

According to the kernel code, the max mirror number of an extent
is 3 not 2:
	ctree.h: 		BTRFS_MAX_MIRRORS	3
	chunk-recover.c :	BTRFS_NUM_MIRRORS	2
just change BTRFS_NUM_MIRRORS to 3, and everything goes well.
